Comparative molecular studies trace our earliest genetic material to Africa.b. Stone tools found in sediments coeval with the earliest H. ergaster (just under two million years ago) are essentially identical with those made by the first stone toolmakers many hundreds of thousands of years before.c. H. erectus evolved in eastern Asia at quite an early date and one branch of the species migrated back to Olduvai in Africa.No human fossils are associated with the first stone tools known, from sites in \Kenya and Ethiopia.

Answer:

a. Comparative molecular studies trace our earliest genetic material to Africa

Explanation:

With the development of the genetics we have been able to come to new findings or confirm some suspicions when it comes to the origin of the humans. The genetic analyses of the human DNA and the other hominids that have died out, as well as out closest ''cousins'' in the animal kingdom, have shown that the earliest human ancestors have evolved in Africa. Over time, as the conditions allowed it, the hominids started to migrate out of Africa and gradually started to settle all around the planet.
